There’s nothing worse than standing in front of a relentless opponent having exerted all your energy – sitting dead in the water, unable to respond with the same work rate.

If you understand how your body supplies energy in a Muay Thai fight, you can train it to not gas out when you need it most! You need Muay Thai fitness, not general fitness.

Why do some fighters gas out? Here’s an excerpt from one of my educational videos explaining specifically what a Thai boxer needs in terms of fitness adaptations to be in the best fight shape.


By understanding qualities in this video such as anaerobic threshold and anaerobic power reserve and applying them to your training, you can literally leap ahead of your opponents. And measuring these qualities really changes the game!

Strength and conditioning coaches can profile an athlete’s performance and compare it to the performance of an elite athlete in the given sport. Then training can target closing the gap, giving you the best possible athletic foundation to compete at the highest level.

I’ve developed a series of easily conducted practical tests for my clients, that allow me to calculate and create a highly specific Muay Thai performance profile.


Do you want to know where you sit on the ‘anaerobic power reserve’ scale shown in the video? I can show you!

Such testing answers these questions:

  • How does your athletic performance rate as Thai boxer?
  • What areas do you need to work on?
  • Are you getting any better?

If you want to know more about this, performance testing and reporting is part of both my Muay Thai S&C Accelerator program here, and Heavy Hitters program here.
